What I'm looking for

I’m looking for a role where I can architect AI-driven Google Ads and tracking systems for B2B SaaS/eCommerce—scaling accounts with rigorous GDPR-compliant data, human-in-the-loop bidding, and measurable ROAS, preferably with room to lead strategy end-to-end.

I’m a Google Ads certified architect with 8+ years of experience, including an insider background as an ex-Google Vendor Partner. I specialize in the technical orchestration of high-scale B2B SaaS and eCommerce campaigns across DACH, US, and APAC—turning legacy account setups into AI-driven architectures using Gemini, ChatGPT, and Claude AI.

I’ve managed $20M+ in lifetime ad spend with outcomes like 523.7% ROAS, a 60% reduction in CAC, and 100% GDPR compliance in tracking and data management. At Threecolts, I built human-in-the-loop intelligence frameworks that increased SQLs by 18% and net-new revenue by 23%, engineered elite install performance (40.6%) and $2.04M in high-LTV merchant revenue (5.2x ROAS), and scaled monthly Google Ads budgets to $50,000+ while improving blended CAC by 22% through first-party data and offline conversion imports.
